DRIVER SUPPORT
||
The previous illustration shows that Pilot
Assist is set to maintain a speed of 110 km/h
(68 mph) and that there is no target vehicle
ahead to follow.
Pilot Assist will provide steering assistance
because it can detect the lane's side marking
lines.

Collision risk warning from driver
support
The driver support systems Adaptive Cruise
Control* and Pilot Assist* can help alert the
driver if the distance to the vehicle ahead
suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol.
Acoustic collision warning signal
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use
approx. 40% of the braking capacity. If a sit-
uation requires more braking force than driver
support can provide, and if the driver does not
apply the brakes, a warning light and audible
warning signal will be activated to alert the
driver that immediate action is required.
WARNING
The driver support system only issues a
warning for vehicles detected by its radar
unit – thus, a warning may come after a
delay or not at all. Never wait for a warning.
Apply the brakes when necessary.
Collision warning symbol on the windshield.
In vehicles equipped with a head-up display*,
a flashing warning symbol will be displayed on
the windshield.
NOTE
Visual warnings on the windshield may be
difficult to notice in cases of strong sun-
light, reflections, extreme light contrasts,
or if the driver is wearing sunglasses or is
not looking straight ahead.
